Alcetas (brother of Perdiccas II)

Alcetas (Ancient Greek: Ἀλκέτας, romanized: Alkétas) was the brother of Perdiccas II, king of ancient Macedonia. Alcetas was the son of Alexander I and an unknown queen; he was a grandson of Amyntas I. Following the unexpected death of Alexander I in 454 BC, Alcetas obtained his own local realm and power base (arkhai).^[1] However, Perdiccas annexed the territory at some unknown point, but ultimately spared Alcetas' life.^[2] He evidently retained some responsibility in his brother's government as Alcetas name follows the king's on a list of Macedonian signatories to a peace treaty with Athens.^[3] Plato, through his interlocutors in Gorgias, wrote that Perdiccas' successor, Archelaus, murdered both Alcetas and his son Alexander.^[4]
